How To Replace or Change a Circuit Breaker in your Electrical Panel & Why it's Tripping

Introduction

This tutorial will guide you through the process of replacing or changing a circuit breaker in your electrical panel, as well as understanding why a breaker might be tripping. Knowing how to perform this task can save you time and money, and help you troubleshoot electrical issues in your home.

Step 1: Gather Your Tools and Materials

Before you begin, ensure you have all necessary tools and safety equipment:

• Tools Needed:
  • Screwdriver (flathead or Phillips, depending on your panel)
  • Voltage tester or voltmeter
  • Flashlight
• Safety Gear:
  • Safety goggles
  • Insulated gloves

Step 2: Turn Off the Main Power Supply

Safety is paramount when working with electricity. Follow these steps to turn off the main power:

1. Locate the main power switch in your electrical panel.
2. Flip the switch to the "Off" position. This will cut power to the entire panel.
3. Use a voltage tester to confirm that the power is off by testing inside the panel.

Step 3: Identify the Faulty Circuit Breaker

Determine which breaker is tripping or faulty:

1. Inspect the breakers in your panel.
2. Look for any breakers that are in the "off" position or tripped (middle position).
3. Try to reset the tripped breaker by switching it to "off" and then back to "on".

Step 4: Remove the Faulty Circuit Breaker

Once you’ve identified the faulty breaker, proceed to remove it:

1. Unscrew any screws holding the breaker in place.
2. Carefully pull the breaker out of the panel. Note how it's connected.
3. If necessary, disconnect the wire attached to the breaker by loosening the screw.

Step 5: Install the New Circuit Breaker

Now, it’s time to install the new breaker:

1. Connect the wire to the new breaker, tightening the screw to secure it.
2. Slide the new breaker into the panel until it clicks into place.
3. Reattach any screws previously removed to secure the breaker.

Step 6: Restore Power and Test the New Breaker

After installation, you can restore power to check if the issue is resolved:

1. Flip the main power switch back to the "On" position.
2. Turn on the newly installed breaker.
3. Test the circuit by plugging in an appliance to see if it functions correctly.

Conclusion

Replacing a circuit breaker can be a straightforward process if done carefully. Always prioritize safety by using proper tools and confirming that power is off before starting. If the new breaker continues to trip, it may indicate a deeper electrical issue that needs professional evaluation. Always consult a qualified electrician if you're unsure or uncomfortable with any step of the process.
